, EENRY w.- MERRI TroF SYRAO TYPE-WRITING- MACHINE.

To all whom it may. coriom'h:

Be it known that I, HENRY W. Mnnmrr, a citizen of the United States, and a resident of Syracuse, in the c'ounty of Onondaga and State oi New York, have invented certain new and specification.

My invention relates to type bar and hanger coni struetions for typewrit'ing machines, and theobjeet, of

said invention is to provide an easy and efficient type bar bearing and to provide a construction in which the parts eanbe readily assembled.

' J Tcrthe above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a Central, vertical front to rear sectional view of a sufiicient number of parts of one form of typewriting machine to illustrate my invention and its application thereto. Fig. 2

, isan enlarged detail transverse sectional view taken through a type bar and hanger, the section being taken on the line a: x of Fig. 3 and looking in the direction of the arrow at said line. Fig. 3 is a longitudinal sectional view of the same taken on the line y y of Fig. 2 and looking in the direction of the arrow at said line. Fig. 4- is a fragmentary enlarged detail side elevation showing the heel or pivotal end Fig. 5 is an enlarged detail end view of one of the hollow sleeves, the view looking in the direction of the'arrow in Fig. 6. Fig. 6 is an enlarged detail side view of the The base 1 of the machine is provided with corner posts 2 surmounted by atop plate 3. A suitable earriage (not shown) travels from side to side of the machine and supports aplaten 4 diagrammatically illustrated in Fig. 1.. Key levers 5 are pivoted at 6 in the base of the machine and associated with each key lever is a restoring spring 7. oted to each key lever at 9 and has aslot 10 in the lower end portion thereof for the reception of a fixed fulcrum rod 11 which extends beneaththe key levers from side to side of the machine and is secured at its ends to the base of the machine. The upper end of each sub-lever is pivoted at 12 to a forwardly extending link 1.; which in turn is pivoted at 11 to a type bar 15. Each type bar has a bifurcated or slotted heel which is fornn-d in the *esent instance by a milling cut to form a cut-out perton in so as to provide two cheek plates 17 that consti- "iift'ile the bifurcated portion. The cheek plates are ountersunk at opposite sides thereof,- as indicated at 18 and 1!), the countersunk portions ing entirely through the cheek plates so as to provide useful Improvements in I Type writing'Maehines, ,of which the following is a of one of the type bars.

An upright sub-lever 8 is piv-.

The tion 18 in the type bar is preferably in Fig. 4, for cooperation with'the serrations 26 on the under side of the head 27 of a sleeve 28. This headed sleeve extends throughone of thecheeks of the type bar and through an eye or opening 29 in the hanger, and terminates before it reaches the head 30'of the operating rivet 31 so that there is a free space 32 between the inner end of the sleeve and the when the parts are assembled, as

order that the rivet and sleeve may have a further countersunk per;

movement towards each other if desired.

, The sleeve 28 preferably hasa smooth bore for the,

reception of the stem of therivet 31 and its head is slightlycountersunk as indicated at 33 to receive the up-set or "headed end 34. the. rivet, so that the outside of the head 34 will It h with the outside of the head of the sleeve and tllat s ide of the cheek l'l'of-tho type bar which contains the countersunk portion 18 as clearly shown in Fig. 2. The head'30 of the rivet 19 'in the opposite check of outermostportion of said head will be flush withthat The sleevh 28 isprefcrably hardened or case hardened and ing for the inner wall of the opening 29 in the hanger, or in other words. it constitutes-the pivotal bearing on which the type bar turns. The rivet 3130s the other hand, is preferably a soft rivet, the stem of which extends through the smooth bore in the sleeve and is or turning the head 34 thereon. This is preferably done by spinning the head with a suitable tool, so that undue pressure will not be exerted upon the bar and an easy pivotal movement is afforded.

It will be seen that the only part ofthe'connection that receives wear through contact with a'movingpart is the sleeve which is hardened and, needs nocliange in form in eonneelingor assembling the parts/whereas the rivetwhieh receives no wear can be made 'soft so that the head 34 can be formed thereon to cornecbthe parts aft er they are assembled.

It will be understood that by the means thus described the type bar and hunger may be readily eonneeted and may be used to take up an" looseness or existbetween the inner side walls of the cheek plates and the outer cooperating side walls of the type bar hanger.

The hanger is preferably provided with two circulargrooves in the opposite sides thereof, as indicated the serrations in the countersunk portion 18 of the type bar, cause the sleeve and the rivet to be locked against rotation relatively to the type bar,'so that the .sleevewnd rivet will turn with the type bar during the printing movements thereof.

A type bar hanger secured to the segment in the manner shown in this case is not claimed herein, but is claimed in my pending application Serial No. 188,080, filed Jan. 7, 1904, and more broadly in my pending application, Serial No. 186,815, filed DecembeI 28, 1903.
